Frequently Asked Questions (FAQ)
Q: What is the difference between 1746-BAS-T and 1746-BAS?
A: The 1746-BAS-T is a newer revision with improved firmware and support for enhanced instruction sets. It is fully backward‑compatible with the original 1746-BAS module.Q: Can this module be used with a 1746-P1 power supply?
A: Yes, the 1746-BAS-T operates on 24V DC supplied through the SLC 500 backplane, which can be powered by any compatible chassis power supply such as the 1746-P1 or 1746-P2.Q: Does the module come with programming software?
A: The module itself includes no software. It is programmed using Rockwell Automation’s RSLogix 500 (or CCW) software, which must be purchased separately. We can provide recommendations on compatible software versions.Q: What is the maximum number of I/O modules I can connect?
A: This depends on the chassis size and addressing limits. With a 13‑slot chassis, you can install up to 12 I/O modules plus this CPU. Additional expansion chassis can be added via DH‑485.Q: Is this module suitable for safety‑critical applications?
A: The SLC 500 basic module is not certified for functional safety (e.g., SIL). For safety applications, we recommend dedicated safety controllers. Always review your application requirements with a qualified engineer.Q: What is the lead time for the 1746-BAS-T?
A: Lead time varies by stock availability. Typically, we ship within 3–5 business days after order confirmation. For urgent requirements, please contact our sales team to check current inventory.Q: Do you offer technical support for this product?
A: Yes, our team can assist with basic programming questions, wiring guidelines, and troubleshooting. For advanced support, we recommend consulting Rockwell Automation’s official resources.Q: Can I return the module if it is defective?
A: We offer a standard warranty against manufacturing defects. Please review our return policy during checkout or contact us for detailed terms.
